Willemite is a zinc silicate mineral with the chemical formula Zn2SiO4 and a minor source of zinc ore. It occurs in several colors and forms, but specimens from the Franklin and Sterling Hill zinc deposits in New Jersey are especially associated with bright green fluorescence under shortwave ultravi...

Lucite® Fluorescent Cast Acrylic is a cast polymethyl methacrylate sheet sold under the Lucite brand in colors formulated for high visual intensity. Its saturated, light-transmitting appearance is used for signs, displays, decorative panels, and other fabricated objects where color is central to the...

Adamite is a zinc arsenate hydroxide mineral that commonly forms yellow, yellow-green, or pale green crystals and crusts. It occurs in the oxidized zones of zinc-bearing ore deposits and is valued by mineral collectors for its crystal forms and fluorescence, which can produce bright green colors und...

Scheelite is a calcium tungstate mineral with the chemical formula CaWO4. It is an important ore of tungsten and is also collected as a mineral specimen because crystals can show bright blue-white fluorescence under shortwave ultraviolet light. Natural scheelite may occur in white, yellow, or other...

Fluorapatite is a phosphate mineral whose chemical structure contains calcium, phosphate, and fluoride. It belongs to the apatite group and can occur in igneous, metamorphic, and sedimentary settings, including as a component of phosphate-rich deposits. Fluorapatite is also important in biology beca...

Powellite is a calcium molybdate mineral with the chemical formula CaMoO₄. It is commonly associated with oxidized parts of molybdenum-bearing deposits and may occur as a secondary mineral. Powellite is notable to mineral collectors because some specimens show bright yellow fluorescence under ultrav...

Apatite is the name used for a group of phosphate minerals, including fluorapatite, chlorapatite, and hydroxylapatite. It commonly forms hexagonal crystals and occurs in igneous, metamorphic, and sedimentary rocks. Apatite is an important natural source of phosphorus and is also used as a gemstone w...

Hyalite opal is a usually colorless, transparent to translucent form of opal with a glass-like appearance and rounded or botryoidal surfaces. Some specimens fluoresce bright green under ultraviolet light because trace uranium or uranyl compounds act as activators in the silica material. The fluoresc...

Fluorite is a mineral composed of calcium fluoride and is the principal source of fluorine in industrial processing. It crystallizes in the cubic system and occurs in many colors, including purple, green, yellow, blue, and colorless, sometimes in bands or zones within one specimen. Fluorite has a Mo...
